Sector de la técnicaTechnical sector
La presente invención está relacionada con la industria dedicada a la captación de energía solar por medio de paneles fotovoltaicos, y más concretamente con seguidores solares.The present invention is related to the industry dedicated to the collection of solar energy through photovoltaic panels, and more specifically with solar trackers.
Estado de la técnicaState of the art
En la actualidad son ampliamente conocido los seguidores solares, los cuales son unas estructuras móviles que fijan una pluralidad de paneles fotovoltaicos al suelo, y donde estos seguidores solares se encuentran configurados para orientar la pluralidad paneles fotovoltaicos para que se mantengan perpendiculares a los rayos del sol, maximizando la producción de electricidad.Currently, solar trackers are widely known, which are mobile structures that fix a plurality of photovoltaic panels to the ground, and where these solar trackers are configured to orient the plurality of photovoltaic panels so that they remain perpendicular to the sun's rays. , maximizing electricity production.
Dichos seguidores solares suelen comprender un eje longitudinal de giro horizontal fijado de manera pivotante sobre al menos dos pilares fijados de manera perpendicular al suelo, donde la pluralidad de paneles fotovoltaicos se encuentra fijada al eje longitudinal de giro por medio de unos medios de fijación (denominados normalmente correas).Said solar trackers usually comprise a longitudinal axis of horizontal rotation fixed pivotally on at least two pillars fixed perpendicular to the ground, where the plurality of photovoltaic panels is fixed to the longitudinal axis of rotation by means of fixing means (called usually straps).
Asimismo, dichos seguidores solares comprenden un actuador configurado para provocar el giro de la pluralidad de paneles fotovoltaicos, ya sea por el giro simultaneo de los paneles fotovoltaicos y el eje longitudinal de giro o por el giro de los paneles fotovoltaicos respecto a dicho eje longitudinal de giro (es decir sin provocar el giro del eje longitudinal de giro), de manera que se consigue que los paneles fotovoltaicos sigan al sol desde el este (en el alba) hasta el oeste (en la puesta).Likewise, said solar trackers comprise an actuator configured to cause the rotation of the plurality of photovoltaic panels, either by the simultaneous rotation of the photovoltaic panels and the longitudinal axis of rotation or by the rotation of the photovoltaic panels with respect to said longitudinal axis of rotation. rotation (that is, without causing the rotation of the longitudinal axis of rotation), so that the photovoltaic panels follow the sun from the east (at dawn) to the west (at sunset).
Este tipo de seguidores solares tienen la desventaja de que dichos ejes de giro son piezas fabricadas bajo pedido, de manera que si por cualquier motivo durante el montaje se requiere que dicho eje longitudinal de giro fuera de diferente longitud (más largo o corto), en el mejor de los casos se requeriría de mucho tiempo y esfuerzo para adaptar la longitud del eje longitudinal de giro en el lugar del montaje, y en el peor de los casos habría que fabricar otro eje longitudinal de giro con la longitud correcta, con el sobrecoste que todo ello conllevaría (no solo del nuevo eje longitudinal de giro si no también del tiempo y esfuerzo malgastado por los operarios).This type of solar trackers have the disadvantage that said rotation axes are pieces manufactured to order, so that if for any reason during assembly it is required that said longitudinal rotation axis be of a different length (longer or shorter), in The best case would require a lot of time and effort to adapt the length of the longitudinal axis of rotation at the assembly site, and in the worst case another longitudinal axis of rotation with the correct length would have to be manufactured, with the extra cost that all this would entail (not only the new longitudinal axis of rotation but also the time and effort wasted by the operators).
Asimismo, este tipo de seguidores solares tienen la desventaja de que en caso de que el seguidor solar tenga que instalarse en terreno irregular, se dificulta enormemente el montaje del mismo, y por tanto se incrementa el coste asociado a dicho montaje.Likewise, this type of solar trackers have the disadvantage that if the solar tracker has to be installed on irregular terrain, its assembly is extremely difficult, and therefore the cost associated with said assembly increases.
Por tanto, se hace necesario un seguidor solar que durante el montaje permita adaptarse a diferentes longitudes, así como que permita un fácil montaje en terrenos irregulares.Therefore, a solar tracker is necessary that allows adaptation to different lengths during assembly, as well as allowing easy assembly on uneven terrain.

Debe entenderse como lateral del panel fotovoltaico los extremos del panel fotovoltaico más cercanos a los pilares una vez montado en el seguidor solar.The side of the photovoltaic panel should be understood as the ends of the photovoltaic panel closest to the pillars once mounted on the solar tracker.
Preferiblemente, los al menos dos elementos filiformes exteriores se fijan a extremos diferentes de una correa fijada al panel fotovoltaico, por lo que se mejora la distribución de las fuerzas generadas por el peso del panel fotovoltaico, así como se mejora el apoyo de los paneles fotovoltaicos, previniendo el balanceo.Preferably, the at least two outer filiform elements are fixed to different ends of a strap fixed to the photovoltaic panel, thereby improving the distribution of the forces generated by the weight of the photovoltaic panel, as well as improving the support of the photovoltaic panels. , preventing swaying.

Descripción detallada de la invenciónDetailed description of the invention
Tal como se puede comprobar en el ejemplo preferente de realización de la figura 1, la presente invención se refiere a un seguidor solar (1) que comprende al menos dos pilares (2) de soporte anclados al suelo, preferentemente dichos pilares (2) se encuentran anclados verticalmente con respecto al suelo, sin embargo, en caso de que el suelo tenga una superficie irregular esto podría variar.As can be seen in the preferred embodiment example of Figure 1, the present invention refers to a solar tracker (1) that comprises at least two support pillars (2) anchored to the ground, preferably said pillars (2) are They are anchored vertically with respect to the ground, however, if the ground has an irregular surface this could vary.
El seguidor solar (1) comprende además de un soporte (3) fijado a los pilares (2) y donde se apoya al menos un panel fotovoltaico (4), preferentemente se apoyan sobre el soporte (3) una pluralidad de paneles fotovoltaicos (4).The solar tracker (1) also comprises a support (3) fixed to the pillars (2) and where at least one photovoltaic panel (4) is supported, preferably a plurality of photovoltaic panels (4).
Tal como se observa en la figura 2, cada panel fotovoltaico (4) se encuentra fijado a al menos una correa (4.1) con la que se apoyan sobre el soporte (3).As seen in Figure 2, each photovoltaic panel (4) is fixed to at least one strap (4.1) with which they rest on the support (3).
Asimismo, el seguidor solar comprende al menos unos medios de actuación configurados para provocar el giro del panel fotovoltaico (4).Likewise, the solar tracker comprises at least some actuation means configured to cause the photovoltaic panel (4) to rotate.
El soporte (3) comprende un elemento filiforme central (3.1) fijado al extremo superior de los pilares (2), entendiendo como extremo superior como los extremos de los pilares (2) que una vez montados en el seguidor solar (1) se encuentran más alejados del suelo.The support (3) comprises a central filiform element (3.1) fixed to the upper end of the pillars (2), the upper end being understood as the ends of the pillars (2) that once mounted on the solar tracker (1) are located farther from the ground.
Preferentemente, las correas (4.1) se fijan de manera pivotante al elemento filiforme central (3.1) por medio de unos elementos de unión (4.2) fijados en el extremo inferior de las correas (4.1) , entendiendo como extremo inferior como el extremo de las correas (4.1) que una vez montados en el seguidor solar (1) se encuentran más cercanos al suelo cuando los paneles fotovoltaicos (4) se encuentran en posición horizontal con respecto al suelo.Preferably, the straps (4.1) are fixed pivotally to the central filiform element (3.1) by means of connecting elements (4.2) fixed at the lower end of the straps (4.1), the lower end being understood as the end of the straps (4.1). belts (4.1) that once mounted on the solar tracker (1) are closer to the ground when the photovoltaic panels (4) are in a horizontal position with respect to the ground.
De esta manera el elemento filiforme central (3.1) actúa como eje de giro del giro de la pluralidad de paneles fotovoltaicos (4). Asimismo, el elemento filiforme central (3.1) sustenta el peso de los paneles fotovoltaicos (4) permitiendo que dichos paneles fotovoltaicos (4) se encuentren alejados del suelo, facilitando con ello su giro alrededor del elemento filiforme central (3.1).In this way, the central filiform element (3.1) acts as the axis of rotation for the rotation of the plurality of photovoltaic panels (4). Likewise, the central filiform element (3.1) supports the weight of the photovoltaic panels (4), allowing said photovoltaic panels (4) to be far from the ground, thereby facilitating their rotation around the central filiform element (3.1).
Además, el soporte (3) comprende al menos dos perfiles laterales (3.3) con sección en "C”, tal como se puede observar en más detalle en las figuras 3 y 4, fijados de manera pivotante respectivamente a cada pilar (2) por medio del elemento filiforme central (3.1).Furthermore, the support (3) comprises at least two side profiles (3.3) with a "C" section, as can be seen in more detail in Figures 3 and 4, pivotally fixed respectively to each pillar (2) by middle of the central filiform element (3.1).
Concretamente el elemento filiforme central (3.1) pasa a través de un agujero pasante de los perfiles laterales (3.3), quedando el perfil lateral (3.3) fijado de manera pivotante con respecto al elemento filiforme central (3.1).Specifically, the central filiform element (3.1) passes through a through hole in the side profiles (3.3), leaving the lateral profile (3.3) fixed pivotally with respect to the central filiform element (3.1).
Asimismo, el soporte (3) comprende al menos dos elementos filiformes exteriores (3.2) que se extienden entre los perfiles laterales (3.3) y que se encuentran fijados a las correas (4.1). Likewise, the support (3) comprises at least two external filiform elements (3.2) that extend between the side profiles (3.3) and that are fixed to the straps (4.1).
Dichos elementos filiformes exteriores (3.2) se encuentran cada uno fijados en extremos diferentes de cada perfil lateral (3.3) y de cada correa (4.1), de esta manera los paneles fotovoltaicos (4) se encuentran bien apoyados sobre el soporte (3), de manera que se disminuye el pandeo de los paneles fotovoltaicos (4), debido por ejemplo al viento o al movimiento de giro del panel fotovoltaico (4).Said external filiform elements (3.2) are each fixed at different ends of each side profile (3.3) and each strap (4.1), in this way the photovoltaic panels (4) are well supported on the support (3), so that the buckling of the photovoltaic panels (4) is reduced, due, for example, to the wind or the rotating movement of the photovoltaic panel (4).
Preferentemente, el elemento filiforme central (3.1) y/o los elementos filiformes exteriores (3.2) son cables tensados, por lo que se consigue cierta flexibilidad en el montaje del seguidor solar (1), asimismo, al ser tensados el elemento filiforme central (3.1) y/o los elementos filiformes exteriores (3.2), estos por su procedimiento de tensado adquieren suficiente rigidez como para evitar el pandeo debido al peso del panel fotovoltaico (4).Preferably, the central filiform element (3.1) and/or the outer filiform elements (3.2) are tensioned cables, so a certain flexibility is achieved in the assembly of the solar tracker (1), likewise, when the central filiform element (1) is tensioned. 3.1) and/or the external filiform elements (3.2), these due to their tensioning procedure acquire sufficient rigidity to avoid buckling due to the weight of the photovoltaic panel (4).
Dado que el elemento filiforme central (3.1) carga con la mayor parte del peso de los paneles fotovoltaicos (4) y actúa como eje de giro, el elemento filiforme central (3.1) sufre más fuerzas (por ejemplo fuerzas de torsión), que los elementos filiformes exteriores (3.2), lo cual reduce su vida útil, por lo que no se descarta que elemento filiforme central (3.1) sea una varilla o que tenga una sección mayor que los elementos filiformes exteriores (3.2).Since the central filiform element (3.1) carries most of the weight of the photovoltaic panels (4) and acts as the axis of rotation, the central filiform element (3.1) suffers more forces (for example torsion forces) than the outer filiform elements (3.2), which reduces their useful life, so it is not ruled out that the central filiform element (3.1) is a rod or that it has a larger section than the outer filiform elements (3.2).
Asimismo, no se descarta que el elemento filiforme central (3.1) se apoye sobre unos pilares intermedios (no mostrados en las figuras) para reforzar el tensado de dicho elemento filiforme central (3.1).Likewise, it is not ruled out that the central filiform element (3.1) rests on intermediate pillars (not shown in the figures) to reinforce the tension of said central filiform element (3.1).
Tanto el elemento filiforme central (3.1) como los elementos filiformes exteriores (3.2) pueden ser de acero (en todas sus aleaciones, calidades y recubrimientos), fibras (de nylon, vidrio o carbono) u otros metales (tales como aluminio, cobre, níquel, etc.).Both the central filiform element (3.1) and the outer filiform elements (3.2) can be made of steel (in all its alloys, qualities and coatings), fibers (nylon, glass or carbon) or other metals (such as aluminum, copper, nickel, etc.).

Asimismo, los medios de actuación comprenden dos poleas (5.2) montadas en unos apoyos (5.2.1) fijados al suelo, una cuerda (5.3) tensada que se extiende en bucle entre las dos poleas (5.2), un motor (5.1) configurado para provocar el giro de una polea (5.2) y dos amarres (5.4), donde cada amarre (5.4) se encuentra fijado por un extremo a la cuerda (5.3) y por el otro extremo o bien a la correa (4.1) de un panel fotovoltaico (4) o bien a uno de los perfiles laterales (3.3), de manera que el movimiento de la cuerda (5.3) provoca el giro de la pluralidad de paneles fotovoltaicos (4).Likewise, the actuation means comprise two pulleys (5.2) mounted on supports (5.2.1) fixed to the ground, a tensioned rope (5.3) that extends in a loop between the two pulleys (5.2), a motor (5.1) configured to cause the rotation of a pulley (5.2) and two moorings (5.4), where each mooring (5.4) is fixed at one end to the rope (5.3) and at the other end either to the strap (4.1) of a photovoltaic panel (4) or to one of the side profiles (3.3), so that the movement of the rope (5.3) causes the rotation of the plurality of photovoltaic panels (4 ).
Preferentemente, y tal como se puede apreciar en las figuras 1 y 2, el seguidor solar (1) comprende dos medios de actuación uno por cada extremo, para provocar el giro de la pluralidad de paneles fotovoltaicos (4) desde ambos extremos del seguidor solar (1), reduciendo la fuerza de torsión sufrida por los diferentes elementos del seguidor solar (1), aumentando su vida útil.Preferably, and as can be seen in Figures 1 and 2, the solar tracker (1) comprises two actuation means, one at each end, to cause the rotation of the plurality of photovoltaic panels (4) from both ends of the solar tracker. (1), reducing the torsional force suffered by the different elements of the solar tracker (1), increasing its useful life.
Preferiblemente, el seguidor solar (1) comprende un dispositivo de control, configurado para orientar la pluralidad paneles fotovoltaicos (4) (por ejemplo, activando los motores (5.1) de los medios de actuación), para que la pluralidad paneles fotovoltaicos (4) se mantengan perpendiculares a los rayos del sol.Preferably, the solar tracker (1) comprises a control device, configured to orient the plurality of photovoltaic panels (4) (for example, activating the motors (5.1) of the actuation means), so that the plurality of photovoltaic panels (4) They remain perpendicular to the sun's rays.
Asimismo, dicho dispositivo de control estaría configurado para que, en caso de vientos fuertes, gire los paneles fotovoltaicos (4) a una posición horizontal con respecto del suelo, reduciendo con ello el efecto de dichos vientos fuertes sobre los diferentes elementos el seguidor solar (1), aumentando la vida útil del mismo. Likewise, said control device would be configured so that, in the event of strong winds, it rotates the photovoltaic panels (4) to a horizontal position with respect to the ground, thereby reducing the effect of said strong winds on the different elements of the solar tracker ( 1), increasing its useful life.
